Outlook 2007 memory leak

[andyrechenberg]

There was a thread posted early last year about this issue and someone
said that this "leak" was not a leak but expected behavior. I wanted
to make sure that this behavior from Outlook 2007 is expected (doesn't
seem like it should be).

I came in this morning and I had about 8 dialog windows from Outlook
saying that my machine was out of virtual memory and I should close
some applications. Looking at Task Manager I found OUTLOOK.EXE to be
using the following:

Mem Usage: 696,092K
Peak Mem Usage: 836,328K
VM Size: 1,733,392K

A virtual memory size of over 1.5GB!?!?! Seems a little excessive to
me for a mail client to use over 1.5GB of virtual memory. I've
disabled all of the non-Microsoft add-ins so none of those should be
the culprit. I did not have this problem with Outlook 2003.

We have MS Support. Should I open a support incident on this issue.
This doesn't seem like it should be accepted behavior.

Thanks,
Andy.

Could you tell us;
-you're mail account type
-size of your mailbox
-size of outcmd.dat
-size of extend.dat
-how much memory is being used in Outlook Safe Mode?
-version of Windows

Did you start with a clean mail profile or has this been an upgrade?

Robert,

Thanks for your response. Here is the information you requested.

Could you tell us;
-you're mail account type

Account type is Exchange

-size of your mailbox

Mailbox on Exchange is 1,093,433KB (a little over 1GB)

-size of outcmd.dat
2KB

-size of extend.dat

Doesn't exist

-how much memory is being used in Outlook Safe Mode?

I can give you a better idea tomorrow after Outlook has been running a
while. I just started in safe mode and it takes a day or two for the
memory to balloon when running in normal mode. Here are the stats
right now:

Mem Usage: 50,260K
Peak Usage: 51,796K
VM Size: 20,584K

-version of Windows

Win XP SP2 with OS and Office patches current as of today (Jan 25,
2008). Outlook 2007 SP1 (12.0.6212.1000)

Did you start with a clean mail profile or has this been an upgrade?

I believe it was an upgraded profile. I didn't delete my old Outlook
2003 profile before opening 2007 for the first time if that's what
you're asking.

I would also look into the number of adds on

I would also look into the number of adds on

As I said in my original post, I've disabled all non-Microsoft add-ins
so if there is a problem running in Normal Mode (i.e. non-Safe Mode),
then the problem lies with one of the Microsoft add-ins. Here are the
MS Add-ins that are enabled (I'm assuming they aren't enabled in Safe
Mode):

MS Exchange Unified Messaging
MS Office SharePoint Server Colleague Import
MS Outlook Mobile Service
MS VBA for Outlook

The only other add-ins I have (which again, are disabled for
troubleshooting this problem) in Normal Mode are :

Calendar Gadget for Windows SlideShow
Google Desktop Outlook Toolbar
MS Access Outlook Add-in for Data Collection and Publishing

BTW, our SMS admin has an automatic reboot package so my machine got
rebooted this weekend so I don't have any new data. I'll continue to
run Outlook in Safe Mode and post my updated numbers here tomorrow or
Wednesday.

Thanks again for everyone's help.

disable all addons
add one by one to find the culprit

Sounds good.

Since opening Outlook 2007 yesterday here are the memory stats:

Mem Usage: 89,648K
Peak: Mem Usage: 91,720K
VM Size: 41,488K

Acceptable.

I'm going to restart in Normal Mode, disable all add-ins and see if
anything blows up. Then, as Sulasno suggests, I'll enable the add-ins
(MS ones first) one at a time and note the usage to find out the
culprit.

Thanks again

OK, are we talking about COM Add-Ins and/or Exchange Client Add-Ins?
Because I only have one Com Add-In enabled but all of the Exchange
Client Add-Ins enabled

Here's what I have enabled in COM Add-Ins now in Normal Mode:
Microsoft Exchange Unified Messaging and that's it. Here are the mem
stats already (Outlook only open for ~4 hours):

Mem Usage: 161,964K
Peak Mem Usage: 162,660K
VM Size: 113, 924K

That's with only one COM Add-In enabled (MS Exchange Unified
Messaging).

Thoughts?

Well it looks like I've found the culprit - Google Desktop Search Add-
in. The past couple of days I've enabled and then disabled the COM
Add-Ins and Exchange Client Extensions one at a time and everything's
be fine. Last night around 5pm I enabled only the GDS Exchange Client
Extension and came in this morning to find OUTLOOK.EXE using over
400MB of RAM and the VM Size was over 390MB.

I've posted in the GDS help discussion group for more help.

For posterity, if anyone is having a similar problem, try disabling
just the Google Desktop Search Add-in to see if it rectifies your
problem by doing the following:

.. Open Outlook 2007
.. Click Tools --> Trust Center
.. Click Add-ins
.. At the bottom of the window pull down the drop-down box that says
'COM Add-ins' and select 'Exchange Client Extensions'
.. Click the 'Go...' button
.. Uncheck 'Google Desktop Search Outlook Addin'
.. Click OK
.. Restart Outlook 2007

I love GDS and I don't really want to install Windows Desktop Search,
but I shouldn't have to restart Outlook daily.

Thanks again for everyone's help.

Andy.
